If you're on a daytime layover, one thing you can do is hire a driver from Hunter's Support. All your baggage, including rifle, will be with you in the vehicle.
Twice I've had Gavin S. from Hunter's Support, He's a retired dentist and drives a VW van with a 5 cylinder Audi motor in it. Plenty of room for the luggage and 2-3 passengers. Gavin is very pleasant and will keep you safe and show you some sights.
